NAIL-DRAWING TOOL.

Application filed March 22, 1927. Serial No. 177,336.

This invention relates to nail drawing tools and more particularly totools of this nature that are embodied in the form of a claw hammer suchas are used by carpenters.

' One of the objects otthis invention is to provide a tool of thisnature which is equipped to grip the shank of anail that has been partlywithdrawn by the main claw of the han'nner, to complete extraction ofsuch nail from a board or the like.

It is a special object of the invention to provide a tool of this naturewhereby a mutilated nail, that cannot further be ex tracted by thehammer claw, may be gripped and quickly extracted. v

A further object of the invention is to provide the tool with means forgripping andextracting any size nail or the like from the smallestto thelargest, one of the novel features being that any one of said devices ormeans may be en'iployed for a wide range of size of nails.

A further object is to so equipthe tool that the novel features thereofwill be equally adapted to right or left handed workmen.

My invention ha many other objects and features which will be more fullydescribed in connection with the accompanying drawing and which will bemore particularly pointed out in and by the ap pended claims.

In the drawing;

Fig. 1 is a view in. side improved tool. showing the thereof on theright hand side.

liig. 2 a similar view of the lelft side thereol.

Fig. 3 is a view in elevation looking in the direction of the arrow inFig. 1.

Fig. 4 is a plan view looking in the direction of the arrow shown inFig. 2.

Fig. is an enlarged fragmentary view more clearly illustrating the nailimping ing equipment.

Like characters of reference designate similar parts throughout thedili'erent figures ot' the drawings.

Although I have shown the device of my invention embodied in acarpenters hammer, my invention may have utilities in ther embodimentsand hence I do not eqi 1i pment hand wish to be limited to the exactform herein shown. As illustrated, the handle of the tool is designatedat 1, and is fitted to the elevation oi my.

socket 2, in the usual manner. The body 3, which 18 formed integral withthe socket 2,

is provided on one end thereof with the of said claw members at 12 and13, and

their lower or rolling faces at 14 and 15, respectively. The fiat end16, .of the body merges into the rolling faces lt and 15, as shown, andthe inner edges 17 and 18 of the claw members (3 and 7, respectively,are in the usual converging relation so as to adapt them for theextraction of any size nail up to the point where the flat end 16 of thehammer rests on or reaches the surface from which the nail is beingextracted. hen, if the nail has not been completely extracted, thedevice of my invention is brought into play, as will now be described indetail, the structure first, and then the operation.

As shown, the upper faces 12 and 13 are recessed at 19 and 20 to agradually increasing depth from points inwardly oi the tips to pointsoutwardly of the bases of said claw members, as will be clearly seen inFigs. 1 and 2. Thus, I form flanges on the lateral edges of the clawnien'ibcrs which flanges areliush with the outside faces of saidmembers, and are indicated. In each flange, in accordance at 21 and withthls invention, I provide a plurality of nail extracting notches, therebeing.

shown in the present construction, two on each side of the hammer. Forconvenience, I will designate said notches by reference letters, and asall the notches are alike in structure and function, i only one need be'described in detail. The smallest notch is indicated at A, and thelargest at B, on the claw member 6, in Fig. 1. In Fig. 2, I have shownnotches. C and 1), tor inter: mediate sized nails. Thus, I equip thetool, for all sized nails used by a carpenter. v

Next referring toFig. 5, I will; describe the particular novel featuresof the nail pulling notch.

The nail E, is the largest size nail for which the tool is equipped toextract and the ill] IOU

material from which the nail has been partly extracted, is designated atF. The notch 13, has an inwardly disposed wall 23 and an outwardlydisposed wall Q-l and a rear wall As will be seen from Fig. 3, theentrance or throat 26, is smaller than the base nearest wall thisfeature serving to prevent the nail from getting out of place, or thehammer from having relativemovement with respect to the nail. when thelatter has once been engaged. Projecting from the inner wall 23, is anail in'ipinging element which is shown to be in thet'orm of a ledge 27,which as shown in Fig. 3, is coincident with one dimension of the wall.Said ledge, as shown, has a sharpened edge which is intended to impingethe nail on one peripheral portion thereoi, and it will be noted thatsaid ledge is disposed closely to the bottom of said notch B. Projectingfrom wall 24, is a companion ledge 28, which is likewise sharpened andwhich is adapted to engage an opposite peripheral. portion of the nailE. It will be noted that the extracting ledge 28, is-in convergingrelation to its .:ompanion ledge 27, and at a higher elevation in thenotch. It-will also be noted that by recessing the members 6 and 7, asshown and described, I can dispose the notches and the ledges toadvantage, leaving room for the nail to bend freely as it being finallyextracted. The wall above ledge 27, need not recede as this wall isalways moving away from the nail, but the upper portion of wall 24,above ledge 28, slightly recedes because it is moving toward the nail.Further, the ledge 53?, projects, as regards its transverse axis, atsubstantially right angles from the wall 23, whereas ledge 28, pro ectsfrom wall Qel at a slight angle upwardly, as I clearly shown in Fig. Bymeans of this construction, I am able to make a large size extractingnotch function with a wide range of size of nail. Thus, in dotted lines,and as indicated at G, I have shown how this same largest sizeextracting notch will function to complete the extraction of thesmallest size nail, and of course. it will be obvious how such notchwould function to complete the extraction of nails of intermediatesizes. It the notch nearest the size nail is employed, the user canobtain a grip nearer the surface I than if a too large size notch isemployed. However, with the range of sizes which I have provided, itwill be clear that the user need not lose time in fitting the notch tothe nail. The notches are so proportioned with respect to the ledgesthat at no time will the walls of the notch engage the nail beingextracted. If the head of a nail has been mutilated, or if the nail hasbeen broken oil, the device of my invention will function to completethe extraction of such mutilated nail which cannot be extracted by theuse of the usual claw.

It will be noted that I have disposed the extracting notches as nearlyas possible toard the tips oi the claw members so that after the mainclaw has been cnmloyed, the extracting notcl'ies can be brought intoplay and employment with the tips of the claw members near the surfaceso that the greatest possible amount ojlf service can be rendered inextracting the nail crunpletely from the material from which a partialextraction has been ellected by the main claw.

It is believed that the device of my invcntion will be fully undcrstmalfrom the fort goii'ig description and while I have herein shown onespecilic form ot my invention, I do not wish to be limited theretoexcept for such limitations as the claims may import.

I claim:

l. A tool, for drawing nails having a claw formed of opposingly actingclaw members, one oi said members having a ,at extracting notch, theopposing walls ol said notch having projecting nail impinging ledges forengagement with opposite peripheral portious oi the shank of the nail tocomplete extraction thereof when the tool is tilted on said claw andholding the nail free from the rolls of said notch.

A tool for drawing nails having a claw formed of curved claw members,one of said members having a nail extractii'ig notch pro vided withsharp projecting nail impinging ledges for ei'igagement with o mositeperipheral portions ol the shank of a nail, one oi. said elci'nentsbeing disposed vertically in said notch above the other to hold the nailtree from the alls of said notch.
